Application filed November as, 1921. Serial no. 517,716.

shoes for receiving stitches by which uppers are attached to the'soles,and to produce a device capable. oi effecting a saving oftime and laborin the above mentioned process and constructed to attain uniformity inthe production of channels.

With the above and other objects in view, the invention comprises theconstruction, arrangement and combination of parts as now to be fullydescribed and. as hereinafter to be specifically claimed, it beingunderstood that the disclosure herein is merely illustrative and meantto in no way limit the spirit of the invention, slight changes indetails of construction and arrangement of parts being permissible solong as within the scope of the appended claims.

In the accompanying drawing forming-a part of this specification,

Fig. 1 is a perspective View otthe novel tool;

Fig. 2 is an elevational view thereof looking from the rear'in Fig. 1;

Fig. 3 is an elevational view of the tool head detached as it wouldappear when lookfrom the front in Fig. 1;

Figs. 4, 5 and 6 are views detailing the slitting blade, the guide arm,and the turning arm, respectively;

Fig. 7 is a longitudinal sectional view of the tool head oi? Fig, 1 orFig. 2-, and

Figs. 8 and 9 are views corresponding with the showing of Fig. 8,disclosing slightly difierent forms of heads and slitting blades.

Referring to the invention as disclosed in Figs. 1 to 7, both inclusive,lOdenotes the shank or handle, 11 the head, 12 the slitting blade, 13the guide arm, and. 14 the turning arm of the tool.

The head is provided with a threaded end 15 adapted to be inserted inthe handle, and

with an oblique end or guide shoulder 16 opposite said threaded endadapted to bear against the shoe sole in a manner to become obvious whenthe device is in use. T he guide arm, slitting blade and turning arm areall separate and distinct from each other and from the head and are adustably attached to said head. That is to say, the guide arm is desi nedto rest upon the surface of the sole as the cutting operation proceecsto regulate the depth of the cut relative to the fiat or plain surfacesof the sole, it having its bearing surface spaced from the plane of thehead atsuch an interval as to insure the proper positioning of thechannel relative to the thickness of the sole, and said arm is providedwith slots 17' to receive screws 18 whereby the guide arm can beadjustably attached to one side of the head; the turning arm is designedto follow the slitting blace and has its edge 19 so positioned withreference to theplane of the blade asto engage the edge of the lip ofthe sole and turn it back or roll it upon the surface of the sole toexpose the channel for access by the shoemaker to facilitate thesucceeding operation of attaching the upper thereto, and said turningarm is provided with slots 20 adapted to receive screws whereby theturning arm can be adjustably attached to the opposite side of he head;and both said guide arm and turning arm desirably protrude for theirfull lengths beyond one face of the head, that face to re ceive theslitting blade, to provide ways 22 between which an attaching olate ofthe slitting blade is positioned, t he plate being adjustably attachedto the head by means 01 a slot 24 adapted. to receive a set screw 25entering the head, and the slitting blade being desirably of taperedformation and disposed at an inclination to the plane of thehead so asto intersect the same and cut diagonally into the body of a sole leatherto produce the channel by v-rhich the leather lip is permitted to foldback relatively to the body of the sole to permit or" the necessarystitching of the upper thereto, all. as will be readily understood.

By the provision or slitting blade, guide arm, and turning arm which areseparate and distinct from each other and adjustably attached to thetool head, a number of conditions of use of the device are bettered andthe device is thus rendered more,

efficient, the construction as so far described being of general curvedformation.

allowing adjustment of the guide and turning arms transvers E the tooland ad justinent of the sl ing blade longitudinally from the obliquelydisposed shoulder. By the provision of the oblique shoulder betterresults in the actual work performed by the tool can be accomplished,said shoulder being disposed with respect to the head so that the entireface of the shoulder will smoothly engage the leather of the sole whencutting, and not, l'lGIQ'lJOfOiG, so that an edge of the working end thehead will tend to dig into the sole leather and retard smooth action ofthe tool.

By the arrangementof the slitting blade between protruding portions ofthe guide arm and turning arm, a more stable blade and a simplifiedconstruction is obtained, this with the necessity of the utilization ofbut single screw for holding the slitting blade to a face of the toolhead.

In Figs. 1 to 7, inclusive, I have disclosed the attaching plate of theslitting blade as arranged upon the flat, smooth face of the tool headto be parallel with said head. In Fig. 8 l. have disclosed a head, oneface of which is provided with an obliquely disposed portion 26 againstwhich the attaching plate of the slitting blade can be adjustablyarranged so that said blade will be at an acute angle with respect tothe head and shoulder, while in Fig. 9, I have shown, a head thecorresponding face of which is provided with a portion 26' of thatirregular conformation permitting the slitting blade to be arrangedeither parallel with the head and perpendicular to the plane of theshoulder, or at any angle with respect to said head and shoulder, theattaching plate 23 of the present slitting blade y utilization of theprinciple of the modification illustrated in Fig. 9, a slitting bladecapable of making a cut of any preferred nature or depth can be.procured.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent is:

l. A tool of the character described, comprising handle, a tool headhaving three longitudinally disposed flat sides and an oblique shoulderupon its outer end, a guide having a fiat shank adjustably secured toone of the said sides of the head, a turning arm also having a flatshank that is adjustably secured to that side of the head opposite saidattached guide, a slitting blade adjustably secured to a side face ofthe head intermediate of the said guide arm and turnof the head to benearer to or farther essence .i, said slitting plate being adjust lelong" .ifclinally of the head toward and J 'oin said oblique shoulderand at an angle with respect thereto.

2. A tool of the character described, comprising a handle, a 'tool headthereon having asmooth obliquely inclined end and three elongated fiatsides, a guide arm ineluding an elongated flat shank positioned againstone of the flat-sides of the head and provided with slots and screws forits ad justable attachment tothe head, a turning arm having an elongatedfiat. shank fitted against a side of the head opposite the guide arm,and a slitting, blade upon a side of the head between said guide andturning 111, the shanks of said. arms forming protruding portionsagainst which said slitting blade is adjustably secured.

A tool of the character described, comprising a handle, a tool headthereon, having a smooth obliquely inclined end and three elongated flatside faces, a guide arm upon one of the faces of said tool head, aturning arm upon a face of said head and opposite said guide arm, and aslitting blade upon a face of said head and between and supportedagainst both said guide and turning arms, said arms provided withprotrading portions between and by means of which said slitting blade islocated.

it. A tool of the character described, comprising a handle, a tool headthereon, having an oblique shoulder upon its end, and three flat sidefaces, a guide upon one face of the tool head adjacent the end there ofspaced from said handle, a turning arm upon said tool head opposite saidguidearrn, a slitting blade adjacent said shoulder and disposed at aninclination tothe plane thereof, and an attaching plate for saidslitting blade adjustably arranged against aface of said head andlongitudinally between and against protruding portions of said arms.

5. A toolas specified in claim l, where in the face upon which theslitting blade is arranged is provided with an irregular portion and theattaching portion of the blade is of general curved conformation,whereby the slittlng blade is angularly ad- 'usted with res 360i tothelane of the obl lique shoulder to makea cut nature or depth.
